Some proponents of global justice question that opening borders is an effective strategy to alleviate global poverty and reduce inequalities between countries. This article goes a step further and asks whether an open borders policy is compatible with the objectives of global distributive justice. The latter, it will be argued, entails the ordering of needs, the assignment of priorities and the preference or subordination of some interests over others. In other words, global justice requires the establishment of conditions and restrictions (...) on mobility. On the contrary, open borders claim an unrestricted and unconditional (not unqualified) freedom of movement, limited only by public health considerations, serious threats to national security or democratic institutions, but not by an aspiration for maximizing global redistributive utility. The main point is that not only would freedom of movement be instrumentalized, losing its presumptive moral force, but ultimately open borders as a remedy of global justice are an oxymoron. The article concludes with an alternative defence of freedom of international movement. (shrink)

This paper investigates one of the central questions in the ethics of migration: is migration a matter of freedom or justice? The former claims that it is a human right, whereas the latter defends a remedial right to immigrate as a way to meet the requirements of global distributive justice. These arguments seem to enter into an intractable contradiction. On the one hand, if freedom of movement is a human right, it should not be subordinated to the maximization of justice. (...) On the other hand, in a non-ideal world an open-borders policy would be of little help in the assignment of priorities, and its redistributive effects would be suboptimal. The solution, I will argue, lies in a package of global redistributive measures. More open borders now can bring us closer to justice, and only then would immigration make sense as a human right.

In 2016, Béziau introduces a restricted notion of paraconsistency, the so-called genuine paraconsistency. A logic is genuine paraconsistent if it rejects the laws $\varphi,\neg \varphi \vdash \psi$ and $\vdash \neg (\varphi \wedge \neg \varphi)$. In that paper, the author analyzes, among the three-valued logics, which of them satisfy this property. If we consider multiple-conclusion consequence relations, the dual properties of those above-mentioned are $\vdash \varphi, \neg \varphi$ and $\neg (\varphi \vee \neg \varphi) \vdash$. We call genuine paracomplete logics those rejecting (...) the mentioned properties. We present here an analysis of the three-valued genuine paracomplete logics. A very natural twist structures semantics for these logics is also found in a systematic way. This semantics produces automatically a simple and elegant Hilbert-style characterization for all these logics. Finally, we introduce the logic LGP which is genuine paracomplete is not genuine paraconsistent, not even paraconsistent and cannot be characterized by a single finite logical matrix. (shrink)

In 2016 Beziau, introduce a more restricted concept of paraconsistency, namely the genuine paraconsistency. He calls genuine paraconsistent logic those logic rejecting φ, ¬φ |- ψ and |- ¬(φ ∧ ¬φ). In that paper the author analyzes, among the three-valued logics, which of these logics satisfy this property. If we consider multiple-conclusion consequence relations, the dual properties of those above mentioned are: |- φ, ¬φ, and ¬(ψ ∨ ¬ψ) |- . We call genuine paracomplete logics those rejecting the mentioned properties. (...) We present here an analysis of the three-valued genuine paracomplete logics. (shrink)
